[PATCH v3 0/9] PCI: rzg3s-host: Add PCIe driver for Renesas RZ/G3S SoC
Posted by Claudiu 3 months ago
From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Hi,

Series adds a PCIe driver for the Renesas RZ/G3S SoC.
It is split as follows:
- patch 1/9:		updates the max register offset for RZ/G3S SYSC;
			this is necessary as the PCIe need to setup the
			SYSC for proper functioning
- patch 2/9:		adds clocks and resets support for the PCIe IP
- patch 3/9:		fix the legacy interrupt request failure
- patches 4-5/9:	add PCIe support for the RZ/G3S SoC
- patches 6-9/9:	add device tree support and defconfig flag

Please provide your feedback.

Merge strategy, if any:
- patches 1-2,6-9/9 can go through the Renesas tree
- patches 3-5/9 can go through the PCI tree

Thank you,
Claudiu Beznea

Changes in v3:
- added patch "PCI: of_property: Restore the arguments of the next level parent"
  to fix the legacy interrupt request
- addressed review comments
- per-patch changes are described in each individual patch

Changes in v2:
- dropped "of/irq: Export of_irq_count()" as it is not needed anymore
  in this version
- added "arm64: dts: renesas: rzg3s-smarc-som: Update dma-ranges for PCIe"
  to reflect the board specific memory constraints
- addressed review comments
- updated patch "soc: renesas: rz-sysc: Add syscon/regmap support"
- per-patch changes are described in each individual patch

What is this based on? I tried v6.16-rc4 and renesas-driver/master. Or
is there a branch I could pull?

This is based on next-20250703. I pushed it here, as well:
https://github.com/claudiubeznea/linux/commits/claudiu/rzg3s/pcie-v3/


Thank you for looking into this,
Claudiu

Thank you, I doubled checked and tested again. Still works, great!
